An innovative concept of use of redox-active electrolyte in asymmetric capacitor based on MWCNTs/MnO₂ and Fe₂O₃ thin films.

ABSTRACT: In present investigation, we have prepared a nanocomposites of highly porous MnO₂ spongy balls and multi-walled carbon nanotubes (MWCNTs) in thin film form and tested in novel redox-active electrolyte (K₃[Fe(CN)₆] doped aqueous Na₂SO₄) for supercapacitor application. Briefly, MWCNTs were deposited on stainless steel substrate by "dip and dry" method followed by electrodeposition of MnO₂ spongy balls. Further, the supercapacitive properties of these hybrid thin films were evaluated in hybrid electrolyte ((K₃[Fe(CN)₆ doped aqueous Na₂SO₄). Thus, this is the first proof-of-design where redox-active electrolyte is applied to MWCNTs/MnO₂ hybrid thin films. Impressively, the M
